Description
Technical field
The present invention relates to the instrument of turning.
Background technology
Tightening of the sub-thread connection of all trades and professions pipe all is to use pipe wrench, and uses pipe wrench to tend to destroy the surface of pipe, and can not measure screw-down torque.Some industry requirement is being tightened the pipe period of the day from 11 p.m. to 1 a.m in reality is produced, and both otherwise destroy tube surface, accurately knows again to have tightened to much moments of torsion.
For example, when tightening the oil pumper packing in the oil field, moment of torsion is big, the packing tension; Will increase frictional force, packing abrasion piece drive motors, power consumption is maximum, and has unscrewed; Packing is crossed pine will leakage of oil, requires to have a best screw-down torque, so development does not promptly destroy tube surface; The instrument that turns that can show moment of torsion again is necessary in producing, and this just requires to develop a kind of new spanner.
Summary of the invention
The present invention proposes a kind of self-clamping type pipe spanner that shows moment of torsion for solving the deficiency of existing pipe wrench.
A kind of self-clamping type pipe spanner that shows moment of torsion; Technical scheme is: it is that upper front end at a wrench body is provided with screw mandrel; Through screw mandrel the clamping plate of a band age of a draught animal are installed, and are provided with the chute that communicates with front end face, be provided with the slippage fixture block of a band age of a draught animal in the chute in the bottom of wrench body; Clamping plate and mobile fixture block are formed the key grip of an adjustable caliber size, are used for the pipe that clamping is turned; Be provided with hand-held in the wrench body rear end, lever of top anterior hinge joint of wrench body, exerting all one's strength of lever held with hand-held the hand grip portion of formation spanner; On wrench body, be processed with vertical post chamber, the post chamber communicates with chute; Be provided with post alive and pressure sensor in the post chamber, the top of pressure sensor is a spherical, and spherical exposes behind the wrench body certain altitude fulcrum as lever; On wrench body, also be provided with the pressure display instrument that is connected with pressure sensor; Be provided with two hinged connecting rods in the chute below the post of living; A rod hinge connection is positioned on the wrench body; Another rod hinge connection is hinged on the mobile fixture block in the chute, establishes a return spring below two connecting rod hinge points, thereby forms the quadric chain of a self-return.
Above-mentioned pressure sensor can be the pressure sensor of using always.
For ease of using, sealing ring is established as lower piston as hydraulic cylinder on the post of living in the vertical post chamber of wrench body, and the housing of pressure sensor leaves certain space as upper piston between upper piston and the lower piston, is full of lubricant grease in the space; And on wrench body, process an outer oil duct that communicates with the space, connect the upward pressure table on the outer oil duct; The end face of the housing of pressure sensor is processed into sphere and exposes wrench body and withstands on the lever, thereby is integrally formed the formula structure.
In order to make mobile fixture block that a bigger amount of movement arranged; The upper piston diameter is greater than the lower piston diameter, and when upper piston moved down, lower piston had the amount of moving down at double; Thereby promote quadric chain bigger leading is arranged, make and move the fixture block pipe that turned of jam-packed more.
Use operation principle and good effect to be: 1. the operator at first adjusts the openings of sizes of clamping plate and slippage fixture block, makes it meet the diameter that is turned pipe, blocks pipe then; The operator holds with a firm grip and hands handle and lever; Lever at first is pressed on the pressure sensor fulcrum, and post alive is moved down and then makes the slippage fixture block clamping tube reposefully that slides left through quadric chain, and is tighter with the clamping force that is multiplied of putting forth effort; Until turning pipe and tightening up, until reaching the moment of torsion that to ask with Passive part.Common pipe wrench is to make age of a draught animal drive pipe by side force owing to do not resemble, so the surface of pipe can not be destroyed.
2. when turning pipe, manometer is sense data directly, can not cause moment of torsion deficiency or moment of torsion excessive.Data on the Pressure gauge have two kinds of display modes: the one, directly show pressure data, and the staff is converted into moment of torsion with pressure data again.The 2nd, according to balance pivot two lateral extents, directly be marked on the manometer after being converted into moment, pointer indication data are exactly the moment of torsion number, use convenient.
3. when the pressure sensor of design when being big or small piston structure, valve piston (post of living) is moving down at double (multiple is a big piston and the ratio of the column diameter square of living) just, thereby the amount of movement of slippage fixture block is increased, and clamping force is bigger.

The specific embodiment
As depicted in figs. 1 and 2; A kind of self-clamping type pipe spanner that shows moment of torsion, technical scheme is: it is that upper front end at a wrench body 5 is provided with screw mandrel 2, through screw mandrel 2 clamping plate 3 of a band age of a draught animal is installed; And be provided with the chute that communicates with front end face in the bottom of wrench body 5; Be provided with the slippage fixture block 4 of a band age of a draught animal in the chute, the key grip of clamping plate 3 and an adjustable caliber size of slippage fixture block 4 compositions is used for the pipe 1 that clamping is turned; Be provided with in wrench body 5 rear ends hand-held 21, wrench body 5 top anterior with lever 7 of bearing pin 6 hinge joints, lever 7 exert all one's strength end with hand the hand grip portion of 21 formation spanners; On wrench body 5, be processed with vertical post chamber, the post chamber communicates with chute; Be provided with post 10 alive and pressure sensor 9 in the post chamber, the dome of pressure sensor 9 is showed out wrench body 5 certain altitudes, exposes the fulcrum of back as lever 7; On wrench body 5, also be provided with the pressure display instrument 20 that is connected with pressure sensor 9; Be provided with left connecting rod 14 and right connecting rod 18 in the chute below the post 10 of living; Left side connecting rod 14 is hinged with right connecting rod 18 usefulness bearing pins 17; Right connecting rod 18 usefulness bearing pins 19 hinged being positioned on the wrench body 5; Left side connecting rod 14 usefulness bearing pins 13 are hinged on the slippage fixture block 4, establish a back-moving spring 15 below the bearing pin 17, thereby form the quadric chain of a self-return.Through back-moving spring 15 top of post 10 alive is withstood on the pressure sensor 9.
As operator during in the hand grip portion application of force; At first lever 7 moves down post 10 alive, when the operator continues the application of force and then turn pipe 1, and pressure sensor 9 output pressure signals simultaneously; On pressure display instrument 20, show force value, learn out torque according to lever principle.
Above-mentioned pressure sensor 9 can be the pressure sensor of using always.
For ease of using, sealing ring is established as lower piston as hydraulic cylinder on the post 10 of living in the vertical post chamber of wrench body 5, and the housing of pressure sensor 9 leaves certain space as upper piston between upper piston and the lower piston, is full of lubricant grease 12 in the space; And on wrench body 5, process an outer oil duct 22 that communicates with the space, connect upward pressure Displaying Meter 20 on the outer oil duct 22; The end face of the housing of pressure sensor 9 is processed into sphere and exposes wrench body 5 and withstands on the lever 7, thereby is integrally formed the formula structure.
In order to make slippage fixture block 4 that a bigger amount of movement arranged; The upper piston diameter is greater than the lower piston diameter; When upper piston moves down; Lower piston just has at double the amount of moving down of (ratio that multiple is big or small radius squared), thereby promote quadric chain bigger leading is arranged, and makes slippage fixture block 4 pipe 1 that turned of jam-packed more.
